Thermal conductivity of single-walled carbon nanotubes has been calculated considering the three-phonon and four-phonon processes. The contribution of the acoustic modes and optical modes in the relaxation rate of the phonon–phonon interaction and hence to the thermal conductivity have been considered. The thermal conductivity has been calculated for the (8, 0), (10, 0), (11, 0) and (13, 0) zigzag semiconducting nanotubes having different radii. It is found that the thermal conductivity increases linearly at low temperatures which is nearly T2 below 30 K and after reaching a peak, it decreases as aT-1 - bT-2 where a and b are constants and b > a at higher temperatures. It is also found that the thermal conductivity increases with increasing radius of the tube due to the independent effect of three-phonon process and four-phonon process. The thermal conductivity is also found to decrease with increasing tube length due to four-phonon process.
